How to write binary data to stdout in python 3?

Question

In python 2.x I could do this:

import sys, array
a = array.array(\'B\', range(100))
a.tofile(sys.stdout)

Now however, I get a TypeErro

In case you would like to specify an encoding in python3 you can still use the bytes command like below:

import os
os.write(1,bytes('Your string to Stdout','UTF-8'))

where 1 is the corresponding usual number for stdout --> sys.stdout.fileno()

Otherwise if you don't care of the encoding just use:

import sys
sys.stdout.write("Your string to Stdout\n")

If you want to use the os.write without the encoding, then try to use the below:

import os
os.write(1,b"Your string to Stdout\n")
